IMPR'OVE MENT'IN"FASTENERS FOR THE MEETING-RAILS OF SASHE S.

Specification forming part of Letters Patent bio-175,1 [0, dated March21, 1876; application filed February 19, 1876.

To all whom it may concern! Be it known that I, TRA eoT'rKARU'rz, ofBrooklyn, E. D., in the county of Kings and State of New York, haveinvented a new and useful Improveinentin Sash-Fasteners, whichimprovement is fully set forth in the following specification, referencebeing had to the accompanying drawing, in which Figure 1 represents afront view of two window-sashes containing my improvement. Fig. 2 is avertical central section of the same. Fig. 3 is a horizontal section inthe plane a a, Fig, 2. Fig. 4 is a cross-section of the fastener,detached, in the plane y 3 Fig. 2. Fig. 5 is alike section in the plane2 2, Fig. 2. Fig. 6 is an inverted plan view of the lockin g mechanism.

Similar letters indicate corresponding parts.

This invention relates to certain improve-- ments in fasteners for themeeting-rails of window-sashes; and consists of a novel construction andcombination of parts, which will be fully hereinafterdescribed, andspecifically pointed out in the claims. In the drawing, the letter Adesignates a 'bolt, oneend of which is provided with a spur,

B, which projects therefrom in a radial direction, and to the other endof which is secured a handle, O, by which-the bolt may be convenientlyturned. This bolt is placed within a case, D, which is so made that itmay be atfixed to a window-sash. The letter E designates catch-plates,two of which are in this example s'hown attached to one of twowindowsashes, F F, one of the catch-plates being situated'near theso-called meeting-rail, and the other near the upper end of the sashF,so that the sash may be fastened in difl'erent positions. Thecatch-plates E are provided with holes at, having lateral branches ofsuch a size as to admit the bolt A and its radial spur.

' Hence, if the case D is secured to the upper surface of themeeting-rail of the sash F, so that ,the end of the boltA projects inthe direction of the other sash, F, and the catch plate or plates E arefastened in a line with. the bolt, the latter, by being pushed forward,enters the opening a in the catch plate or plates; and if the bolt isthereupon turned its radial spur B catches behind the catch-plate,

and by this means the sashes F F are drawn tightly against each other,while at the same time they are prevented from being raised or lowered.By drawing the sashes together they are prevented from rattling, and thewindow is made comparatively air-tight.

It is obvious that two or more catch-plates,

,E, may be cast in one piece, as shown in this example 5 or they may becast separately, and fastened to the sash 111 any desired-manner.

In order to permit of locking the bolt A after it has been connectedwith the catch plate or plates E, I-combine with the bolt a lock ofsuitable construction; and the best form of mechanism which I havehitherto devised for this purpose consists in providing the bolt A witha flat or square part, G, Fig. 4, and arranging thereunder alocking-slide, H, the latter, by being moved under the square portion ofthe bolt, servingto prevent its rotation. To the slide H I have, in thisexample, connected a tumbler, I, which is subjected to the action of aspring, b, and so arranged that it, together with the slide B, maybegrnoved by a key inserted through a hole,c, in the lock-case. Theslide H and concomitant parts are arranged in a case, D, forming part ofthe case inclosing the bolt A.

By the locking-slide H the bolt A is not only prevented from turning,but also from being withdrawn afterit has been locked.

If desired, a device for preventing the withdrawal of the bolt A when itis disengaged from the locking-slide H may also be combined with thebolt, consisting of a groove, d, which extends partly around the bolt,and a second groove, 0, communicating with the first one, and extendinglongitudinally of the bolt. A lug, f, projecting inwardly from thebottom plate of the lock-case D, catches in the groove at when the boltis turned after being disengaged from the locking-slide H, while thesaid lug traverses the longitudinal groove 6 when the bolt is movedbackward or forward.

In the longitudinal groove e is placed a spring, 9, which bears on thelug f when the bolt is pushed back and forth, and by the frictionalcontact of this spring with the bolt the latter is-prevented from movingby accident.

What I claim as new, and desire, to secure by Letters Patent, is-

1. The combination of a locking-slide, H,

plate E, all substantiellyes and for the object specified.

In witness whereof I have hereunto set my TRAUGOTT KARUTZ. WitnessesCHAS. WAHLERS, J. VAN SANTVOORD.
